The C.M. Fines Building is a 20 story office tower in Regina, Saskatchewan, Canada. The 20 story building was completed in 1979. The building was designed by Joseph Pettick and features unusual energy-efficient reflective windows containing gold dust, giving the building its distinctive colour. The building houses the corporate offices of Saskatchewan Government Insurance (SGI). The building is named after Clarence Melvin Fines who was a Provincial Finance Minister in the 1940s and 50s and played a major role in establishing SGI. From 1979 until 1988 it was the tallest building in Regina.The C.M. Fines Building has had a history of structural problems. In 2004, water damage to the building's post-tension cables necessitated a $3.9 million repair. In 2010, the building was evacuated when high winds damaged a piece of the exterior metal cladding, raising concerns that the glass panels, held in place by the metal, would come loose. In 2012, the Government of Saskatchewan released a tender for a new office building for SGI, with the intention to sell the C.M. Fines Building.

Queen Elizabeth II Court is the city block containing Regina City Hall, a 16-storey office tower in downtown Regina, Saskatchewan. The city hall is built in the International Style.Opened in 1976, "he construction manager was Poole Construction Limited and the architect, Joseph Pettick. It cost $10.1 million." It replaced two previous city halls—built in 1885-86 and 1908—and a temporary one in the old post office on 11th Avenue at Cornwall Street.By the time the cornerstone was laid in 1906 for the second, the "gingerbread city hall," "he wooden building which had served as Town Hall and as Regina's first City Hall was no longer sufficient for the city's needs. This is not surprising, since the tiny wooden building was used as City Chambers, the police station, the fire hall, a school, a public meeting hall and a banquet hall."The 1908 building "was grand in scope and size, emphasizing the confidence city fathers saw in the future of the city. Built on 11th Avenue between Hamilton and Rose Streets (where the Galleria Mall now stands), the new building was ornately decorated. It was often known as 'The Gingerbread Palace.' Constructed between 1906 -1908, it came into use in 1908 as a city hall, centre of arts, music and literature, and a banquet hall. Like its wooden predecessor, the massive stone structure was used for everything from lectures to dances – even boxing matches were held within its hallowed walls. However, by 1963, the revered old hall was showing its age and all civic offices were moved to the Old Post Office building. The building sat vacant for two years until it was demolished in 1965 to make room for a shopping centre."

The Prince Edward Building is the current official name of the historic post office building in Regina, Saskatchewan, located at the corner of Scarth Street and 11th Avenue. The site had been occupied by the original Knox Presbyterian Church from 1885 until the land was sold to the government in 1905. The church moved to a new building on the corner of 12th Avenue and Lorne Street.The post office was designed in the Beaux-Arts style by David Ewart, chief architect for the Dominion of Canada. Construction of the post office took place between 1906 and 1907. Its distinctive bell tower was added in 1912, featuring a J. Smith and Sons clock. An addition to the south of the building was constructed in 1929, designed by Regina architects Storey and Van Egmond. Dormer windows in the attic storey were added at the same time. The building functioned as the post office from 1907 until 1956, when the main post office moved to a new building on South Railway Street .The old post office was declared surplus by the federal government in 1962, and was sold to the City of Regina for $100,000. City offices moved in that same year, when they vacated the old city hall on 11th Avenue between Scarth and Rose Streets. The building served as Regina's city hall until the present-day city hall was opened in 1976.In 1981, the Globe Theatre acquired permanent space on the second and third floors of the building. In February 1982, the old post office was one of the first buildings in Regina to be designated as a municipal heritage property.For a time referred to as the Old City Hall Mall, it was officially renamed The Prince Edward Building in 2003 when Prince Edward visited the Globe Theatre. The building currently houses the theatre, small shops and a restaurant.
